Product Description

The Stabilized Soil Block (SSB) Press by Makiga is a manual press machine that produces stabilized soil blocks (SSB). This can be various shapes, interlocking (ISSB) or non-interlocking. Makiga proposes that the press can produce blocks used for affordable housing, water storage and sanitation solutions.

Competitive Landscape

Manufacturing/Building Method

Stabilized Soil Press can be used on a construction site or a small production facility.

Intellectural Property Type


User Provision Model

The user buys directly from Makiga. They can contact the different offices in Africa, inquire directly on the website or contact them in social media to learn more.

Distributions to Date Status

Hundreds of thousands of construction machines have been exported.

System Dimensions


Portability (yes/no)

Yes, it weighs 130kg.

Raw materials used

Soil, Cement

Recommended water content (ratio)


Induced pressure (Mpa)

The press has a compression force of 80-100kN, which is approximately 2.5MPa on the brick surface.

Power source

Manually operated

Finished unit dimensions

29 x 14 x 11.5 cm

Rate of production (units/hour)

500, in an 8 hour day with 4 workers.

Curation duration (days)

14 (wet curing for 7 days, and then dry curing for another 7)

Suitable climate

Not suitable for cold climates unless necessary vapour barriers and insulation can be added. On their own ISSBs and CEBs do not hold up well to freeze/thaw cycles and have a low thermal insulation capacity.

Design Specifications

To manufacture an ISSB using this press, first the soil, cement and water is mixed. The ratio varies depending on the desired outcome. The mix is then placed inside the press and the lever is pushed down to compress the block. After this, the lever is turned to the other side to lift the block out of the press. The brick should be sprayed with water for the next seven days in order to cure it. Finally it must be left to dry cure for another 7 days. The press has four designs to create blocks of different shapes.

  1. Standard Straight ISSB
  2. Wide Straight ISSB
  3. Standard Non-Interlocking SSB
  4. Curved ISSB1
All four have a double action ejection stroke, adjustable mold blocks for different soils, and include training and manuals. Final dimensions of the bricks:
Type of block Height Width Length
Straight double interlocking block 115 140 290
Curved double interlocking block 140
Wide format interlocking block 115 220 230
Straight simple interlocking block 115 140 290
Grooved double interlocking block 115 140 290

Product Schematics

Technical Support

The purchase includes training on operation and maintenance and an illustrated manual.

Replacement Components

It uses motor oil for lubrication. Repair can be made locally with welding and scrap materials.



Manufacturer Specified Performance Parameters

Produce stabilized soil blocks as strong as concrete blocks, in a low cost, eco-friendly and durable way. In an 8 hour day with 4 users, the machine should be able to produce 500 bricks.

Vetted Performance Status

All machines are tested before leaving the plant. The blocks have been tested to have a minimum compressive strength of 2.5 N/mm².


The machine must be placed on a leveled surface so there is no risk of it tipping over. Only trained personnel should operate it.

Complementary Technical Systems

A machine for roof tiles can paired to construct a complete building.
